The 2000 V/µs slew rate enables fast edge preservation for laser pulses or radar returns. Input bias current is 0.4 pA, keeping DC offset drift low with high source impedance.
The 8-WSON (2x2 mm) with exposed pad requires a thermal via array under the pad when running near the 21 mA supply current at elevated temperature.
The OPA858IDSGR has a -3dB bandwidth of 1.2 GHz and a gain-bandwidth product of 5.5 GHz.
The OPA859QDSGRQ1 is an automotive-grade (AEC-Q100) variant with a 900 MHz bandwidth and differential output, versus the OPA858IDSGR's 1.2 GHz bandwidth and single-ended output. The OPA859 also has a lower slew rate of 1150 V/µs. They are not pin-compatible drop-in replacements.
